A Performance Tools Strategy for Petascale Systems


Panel Theme:

The push towards petascale computing platforms is challenging fundamental views towards the programming, operation, and performance evaluation of systems and applications of massive scale. There have been significant advances in the development of performance tools during the last several years of terascale computing. Will the methods and techniques embodied in the tools carry forward to the next-generation of HEC, or is there a need for a paradigm shift in approach?

The panelists will give their position on this question and their perspectives on the general issue of a performance tools strategy for the future HPC systems.
